ObvGreen1/SpotifyControlMod ? reverse-engineered prompt

Build me a client side Fabric mod for Minecraft 1.21.11 that lets me control Spotify from inside the game.

I want it to log in with Spotify using the browser, save the login safely, and keep working with a fallback if the web login is not available. It should let me play and pause, skip tracks, go back, toggle repeat, shuffle, seek, and adjust volume with keybinds and slash commands. Please also add a simple in game menu and Mod Menu settings screen so I can change things without editing files.

On screen, I want a configurable HUD that can show the current song, album art, progress, and synced lyrics, with options for position, size, colors, and opacity. If Spotify is offline, it should show a clear offline state instead of breaking. If you need to, look up current docs online for Fabric, Spotify auth, or lyric fetching details.
